Using Semantic Web Services to Integrate Data and Processes from Different Web Portals

Integration and exchange of information across the Internet is a universally recognized need, in a wide variety of domains. New promising application fields such as Semantic Web Services can improve the integration process in the Web, dealing with the major difficulty of the semantic heterogeneity in the resources, by means of domain ontologies. In this research, we propose an integration system, combining domain ontologies and Semantic Web Services, to provide an integrated access to the information provided by different Web portals in two application domains: biomedicine and geology. Semantic Web Services were designed to encapsulate Web portals in both domains, allowing the system to accomplish the integration in each domain, separately.
